mhz
n. countablen. a unit of measurement for how fast something happens, equal to one million times per second. You usually see this when talking about computer speeds or radio signals.
n. a unit of frequency equal to one million cycles per second. Often used to specify the clock speed of microprocessors or the frequency of radio waves.
The radio station broadcasts at 95.5 MHz.
Older cordless phones often operated on the 900 MHz frequency, which sometimes caused interference with other household electronics.
While modern processors are measured in gigahertz, many specialized microcontrollers still operate in the low MHz range to conserve power and reduce thermal output in embedded systems.
The symbol is MHz; the 'M' is always capitalized to represent 'mega', while 'Hz' represents 'hertz'.
